The Yaesu MD-100A8X desk mic features a cardioid dynamic mic element. It features UP-DOWN tuning (on compatible Yaesu transceivers). There is a scan switch, a switch for PTT (push to talk) and also a lock feature.
On the bottom of the mic base there is a High Emphasis switch and a Low Cut Switch. The mic cable terminates to an Yaesu 8 pin mic plug. This is a 500 ohm mic.
This mic works well with the FT-747, FT-757GXII, FT-840, FT-847, FT-857, FT-890, FT-897, FT-990, FT-1000 and FT-1000MPV. It does not work on some older Yaesu transceivers such as the FT-736R.
